There's not really even a market for it in racing, or at least not drag racing. Most, if not all(I'm not 100% sure b/c some tracks are different) competitive drag racing doesn't allow aftermarket 4 valve heads like that. I think you'd be better off with a high end set of ETP heads, they are working or have finished some canted valve heads for the LSx series motors that flow over 400 cfm and have two different sets of C5R heads.

There have been plenty of manufacturers doing this with their heads although you you see this more with F1 and motorcycle applications. I've seen various heads with up to five valves per cylinder: two intake and three exhaust valves to help with cooldown on the exhaust end. The new Boss 302 has four valves per cylinder. With that added curtain area what do you think help get over 400 horses out of a 5 liter engine?

Still, I would like to see a set.
Maybe use electro-pneumatic actuators hooked to a computer, no camshaft at all ala F1.
Hey, does anyone make a 180 degree crank for these motors, that would be bad ass.

You guys know this guy has a trillion lawsuits on him right now he has ripped of many people over the last few years just throw his name into google and you will find the many ford and chevy guys he's ripped off. Some people have gotten a hold of sets of his ford 302 32v heads but no one has seen a set of the ls heaDS

You can make over 400hp with old school Gen 1 parts and stock type heads on a 5 litre (302). They were doing that in trans am racing back in the 60's. So that wouldn't be anything new. I'd shoot for higher expectations nowadays

Most likely, that's why someone should come up with an LS1 that runs 4 valves, has no pushrods or camshaft.
All electronic valve actuation..
Man, could that puppy rev like no one's business...

Ever take a look at the LT-5 engine specs? The bore and stroke are almost exactly the same as the LS1 engine but its a DOHC. They can rev to 9k (have to be reprogrammed) and still hold speed records. 24 hours at over 173 mpg. Those LT-5s in stock form were "ok" but they were tuned for shit from the factory. Get your hands on one thats been "chipped", exhaust, and 4.10s to take advantage of the 9k rpms you can run and man do you have one kick ass car.

The LT5 is my dream engine.. I have seen a brand new one still crated up...... $10,000....

NHRA class racers drop much more coin than that on heads alone, you just don't see it with LT5's because there really isn't any class to race them in. They don't fit within any rule structures. So they are more of a collectable novelty item.
